EN DOSCOPE.

Patented Oct. 27, 1908.

To all whom 'it may concern.'

rLER, a citizen of the United States,residing in the borough of Manhattan, city, county,

and State of New York, have invented an Improvement in Endoscopes, of which the following is a specification.

Heretofore, endoscopes for use in making examinations for detecting and diagnosing urinary and kindred disorders, have usually comprised a lens tube and a sheath'therefor, in the extremity of which latter a light bulb has been placed in an offset position,- for instance as shown and described in Letters Patent No. 702752 dated June 17th, 1902, and Letters Patent No. `7 23790 "dated March 24th, 1903, both granted to me for improvements in endoscopes and other 'op'- tical instrumenta-wherein the light bulb oEset at the extremity of the sheath is nevertheless parallel therewith, and also as shown in my co-pending application Serial N o. 364306, filed March 25th, 1907, for cystoscopes, in which thelight bulb placed at the extremity of the sheath is offset therefrom at an angle.

Now the object of my present invention is the provision of an endoscope in which a light bulb attachment is secured at the extremity of the endoscope and the instrument is so constructed that the parts of the light bulb attachment are separable and when these parts are separated, a sheath into which thelens tube of the instrument lits, is removable, not only in order that this sheath may be removed but inv order that when the instrument is inserted for the purpose of an examination, the lens tube thereof and its offset end containing the light bulb attachment may be turned at the plea .sure of the, examiner without turning the sheath, which of course contacts with the walls of the organ through which the instrument is passed, thereby overcoming any liability of injury through tearing or otherwise to the said wallsof the organs through which the instrument is passed, and in carrying out my invention, I employ a tube and 'lenses therein, a sheath into which the said tube fits and an electric light bulb attachment, the parts of which are separable and secured to the extremity of the said tube in an offset position and in such a manner that when the separable parts of the Be it known that I, REINHOLD H. WAP- light bulb attachment are separated, the said sheath is removable.

In the drawing, Figure 1 is an elevation of the extremity of an endoscope made in raccordance with my present invention, and

Fig. 2 is a central longitudinal section and partial elevation of the same.

Referring to the drawing, I employ a tube 10 in which a lens 11, together with other suitable lenses, are employed and the tube 10 is provided with an end piece 12 in which and ata suitable inclination the reflecting lens 13 is set, all of which is similar to that shown and described in Letters Patent No. 723790, March 24th, 1903, aforesaid, and 14.- is a sheath into which the lens tube l2 fits and through which the same is adapted to pass. I also employ a socket member 15 which is approximately semi-spherical in outline, the outside diameter being equal to theoutside diameter of the tube 10 and end .piece 12, the socket member 15 is interiorly screw threaded as shown at 16 and so is adapted to receive the screw threaded shank 17 of the tip member 18 in which an electric light bulb 19 is tted, the socket member 15 andthe tip member 1.8 comprising the electric light bulb attachment, the parts of which as will be apparent are separable.

Now in constructing the instrument, the socket member 15 is placed in any desired position in the extremity of the lens tube or the end piece 12 thereof and is secured therein by being soldered thereto as indicated at 20 or otherwise, and as will also be apparent, the light bulb attachment may be placed at any desired odset position and that when the tip member thereof is removed from the socket member 15, the sheath 14 will pass over the socket member 15, whereby the sheath 14 may be removed from the instrument.

I claim as my invention:

, l. An endoscope comprising a tube, a lens therein, a sheath therefor and a light bulb attachment of separable `parts secured to the extremity of the said tube in -such a manner that when the parts of the said attachment are separated, the said sheath is removable from the tube.

2. An endoscope comprising a tube, lens therein, a sheath therefor, a socket member so shaped and secured in the end of the said tube as to permit the said sheath to p ass over the socket member and so be withdrawn from the tube, and an electric light bulbtip adapted to be screwed into the seid'socket member.

3. A11 endoscope comprising e tube, lens therein, e sheath therefor, a semi-spherical socket member soldered in the end olf-the said tube in en oset position and an electric light bulb tip member adapted to be secured in the said secket member, the said socket member being so shaped und secured to the end of the tube that seid sheath Will pass over the seid socket member and so be removable from the tube when the said light -bulb tip is removed.,

4. An endoscope comprising a tube, e lens therein, a sheath therefor, a socket member.

light bulb attachment adapted to be secured' in the socket member.
